BAG FASTENER.

SPECIFICATION forming part of Letters Patent N 0. 695,148, dated March 11, 1902.

Application filed October 28, 1901. Serial No- 80,359. (No model.)

To ail whom it may concern.-

Be it known that LWILLIAM A. FINN, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of NeWYork, have invented certain new and useful Improvements in Bag-Fasteners, of which the following isa specification.

The object of this invention is to provide a bag-fastener of such a nature that when the fold or flap of the envelop is turned down so as to close the envelop the fastener Will not only prevent the flap from being opened, but it will clamp the same in position.

The invention belongs to the class of sainple-envelops which are easily opened, so that the contents can be readilyexamined, and the design is to so arrange the fastener that it will hold the flap firmly when closed, as will now be set forth in detail.

In the drawings, Figure 1 is a perspective view of the end of an envelop with the flap open. Figure 2 is a perspective view of the swiveled portion of the fastener, and Fig. 3 a cross-section of the face portion of the envelop with the swivel attached thereto.

In preparing the fastener I provide a square or rectangular body or blank of metal at, at each corner of which is a small spur 5, by means of which it is secured to the envelop by clenching in the ordinary Way. To this blank I secure a cross-bar by means of a rivet 7, so that it operates as a swivel-plate. The

blank is opened with its body fiat through the middle portion, as shown at 8; but the two outer portions 9 are bent downwardly at their ends with a die, so that when the swivel piece 6 is turned in the position shown in Fig. 2 it will lie flat on the base-piece, but when turned around to a position diagonally across the base-piece there will be a space between the cross-piece and the plate. The object of this will be readily apparent. The flap 10 of the envelop 11 has an oblong eye or opening 12 of substantially the same shape as the crossbar 6. When, therefore, the flap is turned down so that the cross-bar passes through the eye and the latter is turned, the body of the flap adjacent to the barn; will be tightly bound between the base-pieceaalong the sides 9, and thus clamp the flap securely.

What I claim as new is- 1. In a bag-fastener a square blank having ribs for securing same to an object, said blank having the central portion thereof flat,and the two outer portions depressed at the ends, in combination with a cross-bar swiveled centrally to said blank, as set forth.

2. The combination of an envelop having a flap with an eyelet therein, a base-plate secured to the face of the envelop, said baseplate having a flat central portion, and de pressed sides with a swiveled bar secured centrally to said base-plate, as set forth.

Signed at New York, in the county of New York and State of New York, this 1st day of October, A. D. 1901.
